Lots of discussion about excitation, the fluxgate sensor, capacitor, and measurement are described inside this paper. Below are taken from this paper:

The impedance of the parallel resonant circuit is deduced as follows: 1 sCr = Rs + sLs s2 Ls Cr + sRs Cr + 1 (2) or Zr (s) = Rs + sLs (s − s1 ) (s − s2 ) (3) where s1 = −Rs + 2 Ls R2 1 s − 2 Ls Cr 4 Ls s2 = −Rs − 2 Ls R2 1 s − Ls Cr 4 L2 s and From the denominator of (2), the damping factor, ξ , is given by ξ= Rs 2 Cr Ls (4) 1 2π R2 1 − s2 Ls C r 4 Ls (5) When the fluxgate current is increasing and the magnetic core reaches the saturated region, its inductance value drops rapidly and causes the resonant capacitor, Cr , to discharge.

Also, the paper explains info such as current sensor, fluxgate sensor, measurements, and excitation circuit.
